Twelve New Jersey ZIP codes rank among the nation's hottest real estate markets due to rising prices and strong demand in expensive suburbs. Proximity to New York City, transit access, and coastal amenities drive prices, with median listing prices around $1.01M, more than double non-New Jersey areas. Limited housing supply and zoning restrictions contribute to high costs, with home prices now over seven times average income, consuming 40% or more of household income for many families.
